Manifold woes....
Hi Gang,
Is there anyone out there in the aftermarket who makes an intake manifold that will accomodate a 2701 Edelbrock without modifying the hood on my 79? OR am I stuck with using the Q-Jet manifold with an adapter?

Besides the fact that I HATE Quadra-Bog's.... oops... I mean Q-Jets?? lol
I have had several over the years in various vehicles and didn't care for them much. Just one of the problems was leakage between the bowl and base. The fuel would leak out into the manifold over night and result in slow starting in the morning. GM's fix was to epoxy a special plug in the bottom of the carb base. That is one reason I lean toward the Edelbrock one piece carb. Not to mention that they are VERY easy to change jets & metering rods etc.
In this case I can't keep the base gasket under the darned thing. I would almost have to assume the base of the carb is warped. Although I haven't confirmed that. AND have you seen the price of new Q-Jets lately??

Newbs... My q-jet will beat the crap out of any way out of date Carter copy you can throw at it.
Q-jets are cheap and easy to work on, in my opinion. Unlike carters and holleys they are more or less set it and forget it. Once they're tuned they rarely need to be tinkered with because of their superior design.
Lets see you change the cruising mixture on a carter copy as fast as I can change the cruising mixture on my q-jet. Ain't happening.
By the way, 95% of the problems attribute to carburetors are really ignition/timing problems.

OOOOOPSSSSSSS!
The Edelbrock is actually a 1406!! Sorry about the # mixup! 2701 is a Performer series manifold. The 1406 is an electric chock, 600 cfm performer series carb.
Sorry for using the wrong #!!
newbie?? Member since 1999 qualifies me as a newbie?? I bought my first Corvette before MANY on here were born!
The Q-Jets I have looked at online are NOT cheap! Maybe I'm looking in the wrong place??

Any manifold that works with a Holley should work with that Edelbrock, won't it?
As far a Quadra-bogs, they are much maligned. Properly set up, it is an excellent carb. If I had to choose, I would rather have a Holley simply because I can successfully rebuild it. There are people that can build a Qjet and make it good as new, Lars being one of them. I would try to have your Qjet built by an expert before I bought a new carb. My .02

Best place to get a q-jet is from a junk yard off of an old passenger car and then re-jet/rebuild it accordingly. OR find a used Edelbrock 1901 or 1902 and use that. I personally got a 1904 before I realised the primary rods are like gold now. However I recently got lucky and found a bunch of them on ebay for $5 a pair.

You are a newbie if your 53 and have had a lot of Q-J and holleys
I had a brand new 69 Z/28 when I was 16yrs old my first vette at
19, L/48 with a Quadra-flop. They are Ok on a stock motor, Chevy
would not use any of the Quadra-flops on there hi-po motors they
all came with a holley.

Plenty of people on this very forum have 400hp without any problems on a q-jet. If you can't get a q-jet to work with a hi-power engine, you're a newb. Simple as that.

Have always liked Holley Double Pumpers, didn’t get good results with the vacuum secondary Holleys. Cars I've owned always ran better with a DP. Nothing against Quadrajets or vacuum secondarys, just my experience. Probably because I've used them most of my life, I think Holley DP’s work great and are easy to modify and upgrade.

Where's batman to tell us we're all dumb for not just going with fuel injection?
Ey if you want to run a gas guzzling holley have at it. Just don't come in here trash talking the more advanced carburetor. All a carburetor does is mix air and fuel.
By the way, my q-jet isn't GM. It's an Edelbrock.

A simple vacuum secondary holley jetted right will match any Quadra-
flop for fuel milage its just a matter of the right air fuel ratio.
A square bore carb is better for performance, but you don't have to
beleive me CHEVY never ever put a Quadra-flop on any of there performance engines.

They put q-jets on 454s.

OK... OK!!!!
I will drop the subject!! I thought I asked a reasonable question and tried to lend a bit of humor while I was at it. My apologies to all for causing all the uproar!!
53??? where did that come from? Hope it wasn't on my profile.
63 is the right number!
Thanks to all who responded!
Later all,
Ken

holley-hell
450 HP LS6 chevells and the 425hp 71 vette used a holley. the low
performance 454s had a Q-jet. Kalway cant you think up something good on holleys like, hole in the head holley boys, or holley-hell .

I could, but that would bring me down to their level. 
All that tells me is that Chevy had a bunch of holleys that were too big for their normal engines so they had to make something that they could use them on and wouldn't get as much complaining from owners about having to constantly have their car retuned.
"Why do I constantly have to come back to the shop to get this thing retuned?" "You bought the high performance version, what do you expect?" "Damn... I shoulda gotten the one with the quadrajet."

I personally like holley better since i'm used to them. never worked on a q-jet. to me the holleys are easier to work on. that being said my 69 has a q-jet on it and i intend to keep that way. as far as having to keep adjusting on holleys i've been driving with one on another make of car for 4 years now and haven't touched it. car still runs smooth.
